Title: Method and apparatus for optical measurement
Inventor: MIZUKOSHI TOMOHIDE
IPC: G01J3/50
Filed: 1990-10-19
Abstract: PURPOSE:To continuously and correctly enable measurement which is highly accurate and stable itself by aligning a measuring wavelength band to a wavelength band having large spectral absorption of an object to be measured when light from a light source is made incident. CONSTITUTION:Light from a lamp 21 as a light source is incident to and transmits through a blue base F as condensed light 22c by lenses 1',2', and is further incident to a lens 3' so that a total light amount is condensed by a photo diode PD, with which measurement as regards the base F is performed. At this time, combined measuring wavelength of respective spectral sensitivity of the lamp 21, a filter 24 and the diode PD is aligned with an absorption band 51 where a spectrum of the base F indicates the best light absorption so that density of the base F can be correctly measured. Spectrophotometric change of the lamp is measured as a change in color temperature by a colorimeter 50 to manage the lamp 21 in terms of the color temperature wherein a time for replacing the lamp 21 is correctly sensed and its output is constantly maintained at a predetermined value, thereby permitting highly accurate density measurement.

Title: Thermal transfer recording method
Inventor: ASAMI SHINICHI
IPC: B41M5/382
Filed: 1985-12-16
Abstract: PURPOSE:To prevent a dye image from diffusing in directions other than the direction of a receiving sheet and improve the difference in coefficient of thermal expansion between a transfer sheet and a dye gas penetration preventing sheet and the adhesion between the sheets, by using a silicone resin sheet as the dye gas penetration preventing sheet. CONSTITUTION:A dye gas penetration preventing sheet 4 and a receiving sheet 5 are laid respectively on the dye image 3 side and the porous base 2 side of a transfer sheet 1. When heat is applied by, for example, irradiation with IR rays hnu from the sheet 4 side, a heat-sublimable dye image 3 on the transfer sheet 1 is sublimed, and penetrates through a dye gas permeable porous base 2, whereby it is transferred onto the receiving sheet 5 to form a non-reversed transferred image 6. The sheet 4 prevents the dye image 3 from diffusing in directions other than the direction of the receiving sheet 5 at the time of thermal transfer. Since a silicone resin sheet is used as the sheet 4, the difference in coefficient of thermal expansion between the sheet 4 and the transfer sheet 1 is small, and the adhesion between the sheet 4 and the sheet 1 is enhanced.
